A fissionable material that is self-sustainable on a practical level (like U-235), a material to slow down the neutrons caused by the fission (like water), a material to control the chain reaction by absorbing neutrons (like Xe-135), a material to transfer the generated heat to a converter (water again), and something to convert the heat to electricity (like a steam turbine).

Nuclear Fission
The fission happens in the fuel, which is usually in fuel rods inside the reactor. The rods are spaced at a particular distance apart and fill the reactor.
Nuclear fission occurs in fission reactors, a type of nuclear reactor, and in fission bombs, more commonly knows as atomic bombs.
Nuclear fusion reactors do not exist yet as we don't know how to build them. All nuclear reactors are nuclear fission reactors.
Produce heat (energy) from nuclear fission.

False, the fission in nuclear reactors is controlled with the movable control rods.
